Samsung's security updates web page has a vulnerability fixed by the update, CVE-2022-40507, which Samsung describes as “critical.” 67 patches were released to address vulnerabilities classified as high priority. Six have been designated as moderate priority vulnerabilities and one was included in a previous security update.

One of the patches addresses an issue involving the phones' “notification service” that could have allowed an attacker to get their hands on the user's personal information. Galaxy devices running Android 11 to Android 14 were vulnerable. Another patch eliminated a bug that could have allowed an attacker to pair a device with a targeted Galaxy phone via Bluetooth without the device user having to do anything.

Another issue addressed by the update could allow Samsung DeX users in an environment with multiple users to access other users' notifications. It's unclear whether the January security update reinstated Samsung's anti-burn screen protection on affected phones. The company previously said that this feature would return in January in the next update after being removed. This feature shifts the screen pixels slightly to prevent screen burn-in.

Besides the Galaxy S23Galaxy S22 and Galaxy S21, other devices that will receive the January Samsung mobile security update include:

If the update was not automatically installed on your phone, you can do it manually by going to Settings > Software update. These updates include fixes for Android vulnerabilities and those specific to Samsung Galaxy devices.
